Why did the researchers perform sequencing at multiple time points on some patients?
A. Sequences taken at multiple time points enabled scientists to assess whether the patient's immune system was successfully combatting the virus
B. Sequences taken at multiple time points were mistaken made by the researchers where samples were taken independently by two different researchers
C. Sequences taken at multiple time points enabled scientists to assess how the virus was evolving within a patient over time.
D. Sequences taken at multiple time points were experimental controls (technical replicates designed to verify the accuracy of the sequencing procedure
Answer: C. Sequences taken at multiple time points enabled scientists to assess how the virus was evolving within a patient over time.
